Abstract: 13,909. Ratzlaff, J. June 9. Stapling and discontinuous wire-stitching; loose-nailing.-In a machine for f a s t e n i n g buttons, a toothed wheel is provided having teeth suitably arranged to put a staple-former in position to support a button, to operate a punch to cut off a wire staple and to bend it to shape (the wire being previously inserted through the eye of the button), and to operate a clinch bar by which the staple is finally clinched in the fabric when the staple-former is withdrawn by spring pressure. Parts of the machine, such as the button guides, the staple - former, the clinching anvil, and operating - tools, may be made readily removable so that the machine may be used for setting eyelets or for nailing. The machine has a vertical spring-controlled plunger 6, Fig. 1, operated by a treadle 4 provided with a locking- lever 10, the upper end of the plunger having a pin-and-slot connexion with a segmental toothed rocking arm 21 which actuates the toothed operating-wheel 25, the wheel 25 being formed with blank spaces 26. Instead of a treadle, the mechanism may be operated by a motor through gearing, the plunger 6 being eccentrically connected to one of the gears. The punch for cutting off the wire and bending it into a staple over a staple-former 43 comprises a frame 36, Figs. 1 a.nd 7, having two slotted side members working on a pin 38 and normally held in retracted position by springs 39, the frame having teeth 40 on its lower end to engage with the operating wheel 25. Mounted between the side members of the frame 36 is the reciprocating staple-driver 35 having teeth 48 to engage the wheel 25 and a slot 34 at the back to receive and guide the eye of the button, the slot 34 registering with the slot in the button raceway. The lower faces of the driver 35 and frame 36 are bevelled to prevent jamming against the anvil 43. The stapleformer 43, Figs. 1 and 10, is brought into its forward operative position against a coiled spring 44 by means of a pivoted toothed dog 45 engaging rack teeth on the anvil. The dog is actuated by engagement with the teeth of the wheel 25, the blank spaces 26 thereon allowing the dog to return to its normal position when the staple-former has moved forward the desired distance. The clinching anvil 49 is provided with two recesses for turning over the points of the staple, and is carried by a bar 50 having a downwards-extending arm 55 removably fitting in a socket 56 on the side of the machine. The wire 58 for the staples is fed from a wheel 57, Fig. 2, through the eye of a button resting on the staple-former 43 by means of a lever 62 controlled by a spring 69 and having pivoted thereto a spring-pressed gripping lever 64. The rear end of the lever 62 has a roll 68 which bears against an inclined rod carried by the plunger 6. One member of the frame 36 has a cutting edge for cutting off a length of wire. A toothed lever 59 prevents rewinding of the wire and a stop-screw 97 Fig. 1, limits the motion of the wirefeeding mechanism. For nailing the soles of the shoes, a channel 91, Fig. 17, for feeding the nails is fitted through the side of the machine the driver consisting, instead of a frame 36, of a rack-bar 92 with a depending pin 93. An adjustable arm 95, Fig. 16, with an overhanging end 96 upon which the last fits, is attached to the machine frame with the end 96 extending under the driver 93.
